STAPLE DEIVING AND CLENCHING MACHINE.

SPECIFICATION formingpart Of Letters Patent No. 603,438, dated May 3, 1898. A Applioation filed September 10 1897. Serial No. 651,174. (No model.)

To all whom it may concern:

Be it known that I, VALENTINE ZWISSLER, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia,

' and State of Pennsylvania, have invented certain new and useful Improvements in M achines for Inserting and Clenching Metallic Staples, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of machines which are used for the binding together of books or pamphlets, and more particularly to that class of such machineswhere a series of the staples to be forced through and clenched as a binding-staple for the book are contained in a suitable magazine and are antomatically fed forward one by one and inserted in the book.

This invention consists, in substance, of a suitable supporting base and frame, a magazine for holding the staples, means for automatically feeding the same forward into position for insertion, an upwardly-moving table for carrying the pamphlet to be secured together by the staples, means for forcing the staples through the book, means for clenching the staples after being inserted in the same, and means for regulating the movement of the table and the staple-clenchin g device-although it is not to be understood that the invention is limited to a device necessarily comprising at once all of the devices or mechanisms before mentioned, for the invention consists in certain various combinations or arrangements of devices and parts and the construction of certain devices and parts, all substantially aswill be hereinafter more fully described, set forth, and claimed.

Referring to the drawings, Figure 1 is a side view of my improved staple inserting and clenching machine, partially in section, with the parts in the upward or operating position, showing the position of the parts at the moment of the clenching of the staples. Fig. 2 is a like view of said machine with the parts in the lower position ready to be operated. Fig. 3 is a view in perspective of the end of the driving-arm of the machine to which is secured the staple-driving plunger, and Fig.

4 is a top plan view of the forward portion of Fig. 2 on the line at w thereof. Fig. 5 is a view in section of the top portion of Fig. .2 on the line y y, looking to the right. Fig. 6 is a front view, partially in section,of the staple-clenching mechanism before the staple is driven, taken on the line aa of Fig. 7; and Fig. 7 is a view of such clenching mechanism in central vertical section on the line b b of Fig. 6. Fig. 8 is a front view, similar to that shown in Fig. 6, of the upper portion of such mechanism in the position it assumes when the ends of the staple are being driven inward; and Fig. 9 is a view, similar to Fig. 8, of the position assumed by such mechanism when the staple is being fully clenched or driven home to its ultimate position.

Referring to the drawings, the referenceletter A designates a suitable framework of any desired form, upon the top of which is a suitable bar B, preferably of the'shape shown, composed of an upright standard 2 and an outwardly-extending upper bar 3.

Pivoted to the bar B, preferably at the point .marked 4, upon a suitable pivot-pin or shaft is the staple-carrying magazine-bar C, which is so mounted upon such pivot-pin that the outer end thereof will move freely up and down. The staple-carrying magazine-bar 0 is provided with a staple-carrying bar 6, which is located in the slot 7 of such bar 0. The bar B at its upper part 3, at all except its end portion, is in cross-section of substantially the form shown in Fig. 5, and at its extreme outer end is of the form shown in perspective in Fig. 3, it being at this portion composed of an upper bar 8 and a lower bar 9, extending downward at right angles to the bar 8.

Secured at the lower end to the staple-caro rying magazine-bar 0, preferably at about the point shown in Figs. 1 and 2, is a screw 10, which passes up through a suitable hole provided therefor in the top portion 8 of the upper part 3 of the bar 13, and upon the screw 5 10 is screwed a suitable thumb-screw 11, by which the downward movement of the magazine-bar O is limited or by which it may be locked in the extreme upward position to close the staple-magazine, such bar 0 being nor- 10o mally forced downward to the full length allowed by the thumb-nut 11 by a suitable spring 12, located at the ends in sockets 12.

The staples 13 desired to be used in the machine are straddled or placed upon the staplebar 6 and are normally forced forward to the extreme end of such staple-bar by the staplefeeding bar 14, which is provided with the upwardly-extending hook 15, to which is secured a chain 16, passing over wheels 17 and 18, to the end of which chain 16 is secured a weight 19, by the operation of which weight the staples are normally forced forward into working position, or such staple-feeding bar may be forced forward so as to feed the staples by a suitable spring or any other desired manner.

Firmlyserewed upon the extreme outer free end of the magazine-bar C is the face-plate 20, which is preferably in cross-section of the form shown in Fig. 4 and is secured to such magazine-bar C by suitable screws 21. This face-plate 20 is provided with a central slot 22, which is of such width as to receive and hold therein by frictional contact the staples 13 when they are pushed into the slot thereof one by one by the action of the staple-feedin g bar14. The end of the bar B is provided with a stud 23, which is adapted to move freely up and down in the slot 22, and to the outer end of this stud is secured byascrew 24a stapledriver or driving plungeror plate 25, the screw 24 passing for that purpose into a hole 24.

Pivot-ally supported at any suitable point upon the frame, )referably upon the pivot 4, is a table-supporting bar D, preferably of the curved form shown, which is provided at its outer free end with a suitable table 26 for receiving the articles to be bound, which may be of the saddle form shown or of flat or any other desired form.

Carried by the bar D and located immediately beneath the staple feeding and driving mechanism heretofore described and the table 26 is the staple-clenching mechanism. (Shown in detail in Figs. 6 to 9, inclusive.) Such staple-clenching mechanism consists, preferably, of a bar 27, a slide-plate 28, having the slot 2.), adapted to receive the pin 30, secured in the table-supporting bar D, a top plate 31, having a staple-receiving slot 32, and the circular slideways 33, and two stapleclenching plates 34, pivoted to the plate 28 at 35, preferably of the shape shown and having the upwardly-extending point 36, and the bar 27, provided at the bottom with a set-screw 37 for regulating the force of the clenching movement of the staple-clenching plates. The bar 27 is preferably provided on one side with a flatten ed portion 34, registering with the slot or opening 35 in the end of the bar D, the purpose of which flattened portion and slot or opening is to permit of the escape down by said bar and out through said slot of waste or mutilated staples which may be acted upon by the clenching-plates.

Pivotally secured to the frame below the table, preferably upon a suitable lug 38, by means of a pivot-pin 3.), is a lever 40, adapted to receive the pivot-pin 41, and this lever has its rearward end normally pressed downward by a suitable spring 42, and has its position regulated by means of a suitable setscrew 43. Pivoted upon the pivot 41 is a lever 44, pivoted at the rear end, by means of a pivot-pin 45, to the connecting-rod 46, which rod 46 is secured at its upper end to the tablebearing bar D. The lever 44 is provided at its forward end and 011 its upper side with a slide-face, ending in an abrupt entrant hollow 50, beyond which is a hammer-face 51, and secured to the table-bearin g barD at the point shown is a pivot-pin 52, preferably provided with a suitable friction-wheel, mounted thereon as shown in dotted lines in Figs. 1 and 2.

The operation of the device is as follows: The parts being in the position shown in Fig. 2, the operator places the book desired to be stapled upon the saddle-table 26, as shown at G in dotted lines, and presses downward with his foot upon the treadle 47, which draws down the connecting-rod 46, and thus forces upward the outer or hammer-faced end 51 of the lever 44. The table 26 is gradually raised by this movement by the action of the roller and pin 52 upon the slide-face 45) of such lever 44, and as it is gradually raised the book is caught and compressed between the outer end of the magazine-bar C and such table 26, and as the downward motion of the treadle 47, and con sequently the upward motion of the table 26, continues, one of the staples 13 being always in position in the slot 22, beneath the stapledriving plunger or driver 25, and, as the upward movement continues, the staple remains stationaryand is by the action of the driver or plunger 25, as the magazine-bar O continues its upward movement, driven through the book or pamphlet and is by the action of the plates 34, as they are by this upward movement forced into the position shown in Fig. 8, driven inward in its points, as shown, and the moment that the pin 52 reaches the end of the slide-face 49 and drops into the entrant hollow 50 the force which is exerted upon the treadle 47 causes the hammer-face 51 0f the lever 44 to deliver a hammer-like blow upon the set-screw 37, which forces the staple clenching plates, which are then in the position shown in dotted lines in Fig. 8, forcibly upward, so as to elench such staples into the position shown in dotted lines in Fig. 9. Inasmuch, however, as the particular clenching mechanism shown herein is not broadly new and forms no part of this invention, it is not deemed necessary to more fully explain the mechanism thereof, as the same is well known in the art.

It will be seen by an examination of the drawings that the force exerted in the final clenching of the staple by the hammer-face 51 of the lever 44 may be regulated by a proper setting of the set-screw 37 and that the distance of the travel of the table is reg- IIO ulated by a proper manipulation of the setscrew 43, by which the pivot 41, supported in the lever 40, is moved from front to rear of the frame.

The principal object of my invention is to provide an easier and more eflicient method of binding books or pamphlets" by assisting in the feeding to the binding-table of the papers or pamphlets to be bound whether the table be of the saddle form shown in full lines or of the straight form shown in dotted lines in Fig. 2, which may be used with equal facility and effect, for it will be seen that when the operator places the pamphlet or book to be bound upon the table 26 the upward movement of such table facilitates the smoothing and drawing into proper position of such bookor pamphlet and therefore also the insertion of the staples, and it is evident that this upward movement will there-.

fore enable the operator with practice to bind a much larger number of books in a given time than with the stationary tables now in I and I do not intend to limit myself to the ex act form of construction shown or to any particular form of the whole or any of the parts of said device or to the particular manner of combining the same together to bring about.

the desired result, as it is evident that many modifications in the construction, combination, and arrangement of the several parts of my improved staple inserting and clenching machine maybe made without departing from the scope of my invention.
